2022-02-15net/mlx5e: Use FW limitation for max MPW WQEBBsAya Levin8-26/+35
Calculate maximal count of MPW WQEBBs on SQ's creation and store it there. Remove MLX5E_TX_MPW_MAX_NUM_DS and MLX5E_TX_MPW_MAX_WQEBBS. Update mlx5e_tx_mpwqe_is_full() and mlx5e_xdp_mpqwe_is_full() .

2022-02-15net/mlx5e: Read max WQEBBs on the SQ from firmwareAya Levin8-26/+53
Prior to this patch the maximal value for max WQEBBs (WQE Basic Blocks, where WQE is a Work Queue Element) on the TX side was assumed to be 16 (fixed value). All firmware versions till today comply to this. In order to be more flexible and resilient, read from FW the corresponding: max_wqe_sz_sq. This value describes the maximum WQE size given in bytes, thus max WQEBBs is given by the division in WQEBB's byte size. The driver uses the top between 16 and the division result. This ensures synchronization between driver and firmware and avoids unexpected behavior. Store this value on the different SQs (Send Queues) for easy access.

2022-02-15tipc: fix wrong publisher node address in link publicationsJon Maloy1-1/+1
When a link comes up we add its presence to the name table to make it possible for users to subscribe for link up/down events. However, after a previous call signature change the binding is wrongly published with the peer node as publishing node, instead of the own node as it should be. This has the effect that the command 'tipc name table show' will list the link binding (service type 2) with node scope and a peer node as originator, something that obviously is impossible.

2022-02-15scsi: lpfc: Fix pt2pt NVMe PRLI reject LOGO loopJames Smart4-3/+26
When connected point to point, the driver does not know the FC4's supported by the other end. In Fabrics, it can query the nameserver. Thus the driver must send PRLIs for the FC4s it supports and enable support based on the acc(ept) or rej(ect) of the respective FC4 PRLI. Currently the driver supports SCSI and NVMe PRLIs. Unfortunately, although the behavior is per standard, many devices have come to expect only SCSI PRLIs. In this particular example, the NVMe PRLI is properly RJT'd but the target decided that it must LOGO after seeing the unexpected NVMe PRLI. The LOGO causes the sequence to restart and login is now in an infinite failure loop. Fix the problem by having the driver, on a pt2pt link, remember NVMe PRLI accept or reject status across logout as long as the link stays "up". When retrying login, if the prior NVMe PRLI was rejected, it will not be sent on the next login.

2022-02-14RISC-V: Fix IPI/RFENCE hmask on non-monotonic hartid orderingGeert Uytterhoeven1-18/+39
If the boot CPU does not have the lowest hartid, "hartid - hbase" can become negative, leading to an incorrect hmask, causing userspace to crash with SEGV. This is observed on e.g. Starlight Beta, where cpuid 1 maps to hartid 0, and cpuid 0 maps to hartid 1. Fix this by detecting this case, and shifting the accumulated mask and updating hbase, if possible.

When later we chante the mode on the file we strip away this, and other, ACE for authenticated users in set_chmod_dacl() and then just add back/update the modefromsid ACE. Thus leaving the file with a single ACE that is for the mode and no ACE to grant any user any rights to access the file.

Since in the current amd_sfh design the sensor data is periodically obtained in the form of poll data, during the suspend/resume cycle, scheduling a delayed work adds no value. So, cancel the work and restart back during the suspend/resume cycle respectively. Signed-off-by: Basavaraj Natikar <Basavaraj.Natikar@amd.com> Signed-off-by: Jiri Kosina <jkosina@suse.cz>

Add support of rule offloading added to the non-zero index chain, which was previously forbidden. Also, goto action is offloaded allowing to jump for processing of desired chain. Note that only implicit chain 0 is bound to the device port(s) for processing. The rest of chains have to be jumped by actions.

2022-02-14net: wwan: debugfs obtained dev reference not droppedM Chetan Kumar2-0/+38
WWAN driver call's wwan_get_debugfs_dir() to obtain WWAN debugfs dir entry. As part of this procedure it returns a reference to a found device. Since there is no debugfs interface available at WWAN subsystem, it is not possible to drop dev reference post debugfs use. This leads to side effects like post wwan driver load and reload the wwan instance gets increment from wwanX to wwanX+1. A new debugfs interface is added in wwan subsystem so that wwan driver can drop the obtained dev reference post debugfs use. void wwan_put_debugfs_dir(struct dentry *dir) Signed-off-by: M Chetan Kumar <m.chetan.kumar@linux.intel.com> Signed-off-by: David S.

2022-02-14net: dsa: realtek: realtek-smi: clean-up resetLuiz Angelo Daros de Luca1-7/+13
When reset GPIO was missing, the driver was still printing an info message and still trying to assert the reset. Although gpiod_set_value() will silently ignore calls with NULL gpio_desc, it is better to make it clear the driver might allow gpio_desc to be NULL. The initial value for the reset pin was changed to GPIOD_OUT_LOW, followed by a gpiod_set_value() asserting the reset. This way, it will be easier to spot if and where the reset really happens. A new "asserted RESET" message was added just after the reset is asserted, similar to the existing "deasserted RESET" message. Both messages were demoted to dbg. The code comment is not needed anymore. Signed-off-by: Luiz Angelo Daros de Luca <luizluca@gmail.com> Acked-by: Arınç ÜNAL <arinc.unal@arinc9.com> Signed-off-by: David S. Miller <davem@davemloft.net>

Whenever rt6_uncached_list_flush_dev() swaps rt->rt6_idev to the blackhole device, parts of IPv6 stack might still need to increment one SNMP counter. Root cause, patch from Ido, changelog from Eric :) This bug suggests that we need to audit rt->rt6_idev usages and make sure they are properly using RCU protection.
